rerail

Assuming the verb 'to rail' is used in the context as 'to have sex' or 'to fuck', to re-rail is to have sex with someone again/ multiple times; to rail again with a linguistic and harmonious sound (re-screw and re-fuck just don't work!)
-Where's your friend?
--Oh, probably upstairs railing some dude.
-Really! When she gets back, she better be down to rerail.

Did that girl ever call you back after your one night stand?
Of course, she couldn't get enough. We rerailed before Church on Sunday!

Thanks to John's rerailment, the conversation went on as intended.

Thread rerailing

The act of bringing a horribly-derailed thread back on track, much to the annoyance of the idiotic derailers.
I've always loved CR's subtle thread rerailing.
